Abstract

Abstract @ A watering system for areas for the growth of plants with the water being supplied from below with respect to the plants to be grown comprises an area for the growth of the plants which comprises a watertight backing upon which a watering mat has been placed. The watertight backing comprises a waterproof channel element sheet (3) having hollow parallel channels separated from one another by partition walls. At its face in contact with the watering mat (5) the channel element sheet is provided with microfissures or microholes (4) which penetrate into the separate channels enabling water supplied at one of the transverse open ends of the channel element sheet (3) to be sucked into the channels and from there up through the microfissures or microholes (4) and into the superposed watering mat (5). The channel element sheet (3) preferably consists of polypropylene plastics pigmented black, and the watering mat (5) preferably consists of a conventional glass fiber mat of randomly oriented fibers.
